Why don’t you incorporate some treasure hunting into your camping experience? Try geocaching.
A geocache is a hidden “cache”. Follow the clues to find it. Armed with map coordinates and a GPS enabled device, find a hidden geocache in your camping location, or en route during the drive.
Once you find the geocache, sign the logbook inside, then log your find online. If you take something from a geocache, replace it with something or equal or greater value. Be discreet … don’t let the muggles see you searching, or you’ll give the game away.
